15. Buffer Functions (Polling)
The procedures in this section are used to retrieve data that has been
collected from the PBX. NetLink II offers three different polling methods:
1. Menu Driven: NetLink II is contacted via modem or Console Port,
and the Buffer Functions Menu is used to release data.
2. Command Driven: NetLink II is contacted via modem or Console
Port, and ^Bxx commands are entered at the command prompt to
3. Push: NetLink II automatically downloads records via TCP/IP
connection to your SFTP or FTP server.
4. Server: NetLink II is conﬁgured to function as an SFTP or FTP
server. An SFTP or FTP Client is used to retrieve stored data from the
NetLink II Unit.
15.1. Memory Partitions and Shared Data
After data is collected from the PBX, it is stored in NetLink II's ﬂash
memory. Stored data can be retrieved via the Console Port, Modem Port,
Network Port, Push function, or Server function. In order to prevent
conﬂicts when two ports attempt to access the same data, partitions are set
to temporarily grant "ownership" of a speciﬁc type of data to a speciﬁc port.
For example, the Console Port may own all data received via the serial PBX
Port, or the Modem Port may own all records that matched Alarm Filter 1.
When a partition is set for a speciﬁc command port, other command
ports will not be able to access the partitioned data. For example, if the
Console Port partition is set to include data received via PBX IP Port, then
the Modem Port will not be able to access this data until the partition is
These partitions also simplify the process of clearing data after it has been
read. After downloading data from your command port partition, command
^B25 or the Item 5 in the Buffer Functions menu can be used to clear the
partition. Note that records that are received after the partition is set will
not be erased. Once a partition is set, it will remain in effect until the
partition owner exits command mode, invokes one of the partition release
commands, or the FTP/SFTP action is completed.
